gheny and State of Pennsylvania, have in-.

`vented certain new and useful Improvements t following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and `useful improvements in fountain-pen attachments, and has for its objectthe provision of "novel means whereby the ordinary pen may y t be easily converted intoa fountain-pen.

t i object to provide an attachmentthat may be t `The present invention has for its further easily placed in position and readily removed from engagement with the pen-point when l desired.

My invention further contemplates to construct an attachment of the above-described lcharacter that will be extremely simple in construction, strong, durable, comparatively i t inexpensive to manufacture, and highly efficient in its operation. y

The present invention still further aims to provide a novel form of attachment the forward end of which may constantly engage Hthe under side of the pen-point, thus prou ducing a certain movement of the attachmentv against the pen-point when the pen is in use t lthat will automatically feed thepen-point y and will serve to cut the dry ink that would t In describing the invention indetail refer-` ence is had to the accompanying drawings, forming apart of this, specification, and

t `wherein likenumerals ofreferenoefindicate like parts throughout the several views, in which- Figure 1 is a perspective view of the pen,

` showing my improved attachment applied thereto. Fig. 2 is a longitudinal verticalsectional view thereof. Fig. 3 is an under plan `view of the pen-point and attachment. Fig.

4 is a perspective View of the attachment. Fig.- 5 isLa top plan view thereof. Fig. 6 is a side elevation of the same. Fig. 7 illustrates enlarged side elevations of the pen-point and attachment, showing the movements of the forward end of the attachment against the under face of the pen-point.

In the drawings the reference-numeral 1 represents a suitable penholder, and 2 the pen-point secured therein.

The reference-numeral 3 represents the atlfachment, carryingthe semicircular portion 4: at the rear thereof, the contracted neck portion 5, and the downwardly-curved! portion 6, which has tapering sides 7 and slightlytapering walls 8, the latter tapering inwardly and terminating in the square nose 9, which square nose forms a contact with the under face of the pen. An air-space 10 is formed between the forward portion of the pen-point and attachment, which, together with the opening 12, formed in the pen-point, will give proper vent to the reservoir.

Theoperation of my improved pen attachment is as follows: The pen is dipped into the ink in the usual manner, which will fill the reservoir, the ink iiowing into the same throughthe openings 10 and 12. When the pen is in use, by exerting pressure upon the point of the same the square nose of the attachment will continuously serve to feed, and by the forward and rearward movement of the nose the clogging of the reservoir is prevented. Furthermore, in case the ink has become dry when the pen is not in use for a considerable length of time the nose and forward end of the attachment will serve to cut the dry ink that may have accumulated during the inaction of the pen. lWhen it has been found that the attachment has become worn out or the material haslostits resiliency, a new attachment maybe easily inserted in the penholder. 'l

The many advantages obtained by the use of my improved attachment will be readily apparent from the foregoing description, taken in connection with the accompanying drawings.

It will be noted that various changes may be made in the details of construction Without on a horizontal plane, a contracted neck porlo departing from the general spirit of my intion, and a square forward end, as specified.
